Answer:
D. I, IV, VI, and VII
Explanation:
DNA polymerase III has both 5' to 3' polymerization activity and 3' to 5' exonuclease activity (the proofreading). DNA pol III requires divalent magnesium ions for its polymerization and proofreading activities. Here, the magnesium ions serve as cofactor.
DNA polymerase III cannot start the process of synthesis of new DNA strand de novo and uses an RNA primer synthesized by primase enzyme. The polymerization activity of DNA polymerase III elongates the RNA primer in 5' to 3' direction. The primers are removed by 5' to 3' exonuclease activity of DNA polymerase I.
During polymerization, the DNA polymerase III uses existing DNA strand as a template. The four dNTPs namely deoxyadenosine triphosphate (dATP), deoxycytidine triphosphate (dCTP), deoxyguanosine triphosphate (dGTP) and deoxythymidine triphosphate (dTTP) are added to the RNA primer according to the sequence of DNA template.

Explanation:
This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).
In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:
RRYY- RY, RY, RY, RY
RrYy- RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:
RRYY (4)
RRYy (4)
RrYY (4)
RrYy (4)
According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.
This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%

Answer:
The large deep groove or indentation that separates the parietal and frontal lobe is the central sulcus.
Explanation:
The central sulcus, one of several grooves seen between folds of the cerebral cortex, lies between the frontal and parietal lobes. It separates the parietal and frontal lobes.
